IMPALA-10223: Implement INSERT OVERWRITE for Iceberg tables
This patch adds support for INSERT OVERWRITE statements for
Iceberg tables. We use Iceberg's ReplacePartitions interface
for this. This interface provides consistent behavior with
INSERT OVERWRITEs against regular tables. It's also consistent
with other engines dynamic overwrites, e.g. Spark.
INSERT OVERWRITE for partitioned tables replaces the partitions
affected by the INSERT, while keeping the other partitions
untouched.
INSERT OVERWRITE is prohibited for tables that use the BUCKET
partition transform because it would randomly overwrite table
data.
Testing
* added e2e test
